Stable polysiloxane moulding material hardenable by

摘要

Storage stable, plastic org. polysiloxane moulding materials, which can be converted into elastic formed bodies or coatings by action of moisture or air at temps. below 50 deg.C, are prepd. by mixing (I) an alpha, omega-dihydoxypoly (diorganosiloxane), which may contain upt to 10 mole % siloxane units of (I), (II), an N-contg. org. Si cpd. (II) as crosslinking agent, (III) opt. fillers, and (IV) opt. an alpha,omega-bis (trimethylsiloxy) poly(diorganosiloxane). CH3SiO3/2 (RO)3SiCH (R')N(R2)-R3 (RO)3Si-CH(R)- (RO3SiCH(R')N(R2)CH2CH2- R = 1-4C alkyl; R' = H or methyl; and R3 = h, alkyl, cycloalkyl, aminoalkyl, (methylamino)alkyl, (dimethylamino) alkyl, group (III) or group (IV).
